UNIROI Pinpointing Metal Detector

Update: customer service helped us solve the problem. Don’t use battery provided. Buy a high end one or it will alarm if not sufficient battery power. Bought this for my boyfriend as a birthday present. My niece has one and she loved it. Took it out this weekend and had nothing but issues. Starts beeping and we think it finds something. We dig and look but it will beep nonstop even if we hold in air. Have to unscrew end with battery to get it to stop, hold over same place and nothing. I am going to reach out to customer service to see if they can help. Past 30 day return since I had it for weeks before his bday. Will update when they respond.
